From the article:
This is all theoretical, of course. The study authors are both mathematical physicists who use modeling to understand complex systems, ranging from complicated biological processes to fiddly social systems. ...
Forest is also taken as a proxy for all resources, which could be seen as oversimplistic. ...
Nevertheless, the study paints a compelling image of how rampant deforestation and population collapse threaten human society as a whole.
The study primarily looks at deforestation and our consumption of trees. Trees are an invaluable asset for humans and the wider ecosystem. Not only do they support natural and human food systems but they also are a lynchpin in a number of important systems, such as the carbon cycle, oxygen production, soil conservation, and the water cycle. As such, the researchers say deforestation will soon mean there are not enough resources to maintain the global population, at which point there will be a "disastrous collapse" of the population.

Based on the current resource consumption rates and best estimate of technological rate growth our study shows that we have very low probability, less than 10% in most optimistic estimate, to survive without facing a catastrophic collapse.

- jandrese 3y agoThis kind of modeling far too often assumes that current (unsustainable) rates of consumption will continue right up to the point the last tree is cut down. In real life as resources become strained they also become expensive and people start finding alternatives or change behavior to be more efficient. This blows out the long term forecasts time and time again. It is important to recognize where we are consuming resources too destructively, but it is not a death sentence for civilization.
- myshpa 3y agoThey are aware. From the article: At the current rate of deforestation, all of Earth’s forests would disappear in 100 to 200 years. However, the study predicts that the scarcity of forests will start to cause problems long before all of the planet’s trees are gone. “Clearly it is unrealistic to imagine that the human society would start to be affected by the deforestation only when the last tree would be cut down,” they write. “The progressive degradation of the environment due to deforestation would heavily affect human society and consequently the human collapse would start much earlier.” > It is important to recognize where we are consuming resources too destructively It's not only about resources. https://www.nature.com/articles/s41893-023-01157-x https://www.nature.com/articles/s41893-023-01157-x Earlier collapse of Anthropocene ecosystems driven by multiple faster and noisier drivers https://phys.org/news/2023-06-ecological-doom-loops-ecosystem-collapses-sooner.html https://phys.org/news/2023-06-ecological-doom-loops-ecosyste...

- sillywalk 3y agoWithin decades there will be chunks of the earth around the equator housing hundreds of millions of people that will be literally uninhabitable. i.e. the wet-bulb temperature will be higher than a human can tolerate. This year people in Arizona are getting third degree burns from falling onto asphalt. Extreme weather will make agriculture on any scale impossible, because it'll be drought or floods or both. Even if we stop all emissions immediately. Humans can survive in this temperature in the same way they can survive under water, not for very long.
